On contact with acids or water, calcium phosphide releases phosphine, which ignites spontaneously. Calcium (ˈkælsiəm is the Chemical element with the symbol Ca and Atomic number 20 In chemistry a phosphide is a compound of Phosphorus with a less electronegative element or elements Phosphine is the common name for phosphorus hydride (PH3 also known by the IUPAC name phosphane and occasionally phosphamine.
Metal phosphides have been used as rodenticides. Rodenticides are a category of Pest control Chemicals intended to kill Rodents Single feed baits are chemicals sufficiently A mixture of food and calcium phosphide is left where the rodents can eat it. The acid in the digestive system of the rodent reacts with the phosphide to generate the toxic phosphine gas. This method of vermin control has possible use in places where rodents immune to many of the common poisons have appeared. Other pesticides similar to calcium phosphide are zinc phosphide and aluminium phosphide. Zinc phosphide ( Zn3[[Phosphorus P2]] is an Inorganic Chemical compound. Aluminium phosphide is the Chemical compound with the formula AlP
Calcium phosphide is also used in fireworks, torpedoes, self-igniting naval pyrotechnic flares, and various water-activated ammunition. A firework is classified as a low explosive pyrotechnic device used primarily for aesthetic and entertainment purposes The modern torpedo (historically called an automotive automobile locomotive or fish torpedo is a self-propelled explosive Projectile weapon launched above or below A flare, also sometimes called a fusee, is a type of Pyrotechnic that produces a brilliant light or intense heat without an Explosion.
During 1920's and 1930's, Charles Kingsford Smith used separate buoyant canisters of calcium carbide and calcium phosphide as naval flares lasting up to ten minutes. Sir Charles Edward Kingsford Smith MC, AFC (9 February 1897 - 8 November 1935 often called Charles Kingsford Smith or by his nickname Smithy, was a well-known Calcium carbide is a Chemical compound with the Chemical formula of Ca[[Carbide C2]]
It is speculated that calcium phosphide was an ingredient of some ancient Greek fire formulas. Greek fire was a burning-liquid weapon used by the Byzantine Empire.
